python sha256 加盐

在 Python 中使用 SHA256 加盐的方法如下：

import hashlib
import os

def hash_password(password, salt=None):
    if salt is None:
        salt = os.urandom(16).hex()  # 生成随机盐值

    password = password.encode('utf-8')
    salt = salt.encode('utf-8')

    hashed_password = hashlib.sha256(salt + password).hexdigest()

    return hashed_password, salt

# 示例用法
password = "mysecretpassword"
hashed_password, salt = hash_password(password)

print("Hashed Password:", hashed_password)
